The Mainstay Composite Liner was originally developed by United States Steel Corporation as a process for lining uncured reinforced concrete pipe (photo on the left). The USS Chemicals division performed the first commercial application of Mainstay in 1962. Several million square feet of Mainstay was applied by U.S. Steel crews over the following nine years. In 1971, U.S. Steel decided to divest its coatings interests, including Mainstay. Madewell Products Corporation was established soon thereafter to manufacture Mainstay products. Over the last 50 years, Mainstay brand products have been used to line concrete surfaces in sanitary sewer and industrial environments throughout the U.S. and abroad. Today, Madewell Products manufactures a variety of cementitious and epoxy products, including aquarium lining systems, moisture mitigation systems, and floor leveling materials. Madewell also manufactures specialized application equipment for use with these materials. All products and components are manufactured at Madewell`s headquarters in Alpharetta, GA.

Madewell Products Corporation manufactures industrial coatings, mortars, and vinyl ester products used for the restoration of structures in pulp and paper mills, chemical processing plants, and other facilities. These products are also ideally suited as tank linings for most chemical immersion applications.

Madewell Products Corporation manufactures Mainstay SLU-HC Premium Self Leveling Underlayment, and a moisture mitigation product called Permaseal Platinum that work synergistically to form the Mainstay Composite Top system. When used together, these products provide a subfloor that is tightly bonded, smooth, flat, and free of any issues associated with moisture and alkalinity.

Madewell`s unreinforced and laminate lining systems have been used to provide corrosion protection and waterproofing in aquariums and zoos throughout the United States and Canada. Clients include the Georgia Aquarium, the National Aquarium in Baltimore, the Chattanooga Aquarium, and many others.

Madewell manufactures a complete line of application equipment used to mix, pump, and spray heavy bodied restoration mortars and high build, 100% solids corrosion barrier coatings.
